Abstract
Abstract A flexible skid is mounted between pressure-sensitive copy paper, and a follower roller of a transducer holding the paper marking stylus. The skid, held in place by a plate retained on the transducer housing by the magnetic field and pressuresensitive adhesive, slides on the paper as the transducer traverses the paper and, while providing the compliance needed for proper stylus functioning, remains comparatively free of dirt accumulation.

Claim 1
Independent Claim
178 words
In combination with a transducer assembly including a housing and a stylus mounted to said housing for marking a markable medium traversable by the transducer assembly, stylus control means comprising: a stylus drive member in said housing and coupled to said stylus and operable to drive said stylus in a direction away from said housing toward said medium; an arm pivotally mounted to said housing to pivot about a pivot axis, and having connector means extending therefrom to said drive member at a point remote from said pivot axis; and skid means mounted to said housing, said skid means having a skid having a portion immediately adjacent said stylus and slidable on the surface of said medium and coupled to said arm at a point remote from said pivot axis for operation through said arm and connector means to maintain a limit on the position of said stylus with respect to said medium surface, said skid being relatively movable to a limited extent with respect to said arm to adapt to variations in contour of said medium surface.
